The volcanic rock nomenclature follows the one of Le Bas et al (1986)
Size estimates for some lava flows associated with monogenetic vents of the Shamiram Plateau and elsewhere on the flanks of Aragats volcano. The input parameters for the lava flow simulations were based on the observed characteristics of the smaller-volume flows. Volcanoes located within the area of the Shamiram Plateau appear in italic font. Size estimates for the 5 largest lava flows on the flanks of Aragats volcano are listed last.
